First time solo grow with autos

Planted about 8 unknown African sativa strain seeds alongside my 2 feminised autos. I realise these photoperiod plants will create headaches come flowing time alongside the autos, but it is really just to spread the risk and see how the different plants react as I learn. I will likely discard or isolate the photoperiods when their light needs change. I have loads of unknown sativa seeds so plan on using these as cannon fodder. Middle of winter here in Western Cape, South Africa, my plan is to move from inside cupboard to grow tent in the garage, once the weather warms up in the next few weeks. After some initial problems with seed medium, I got a good batch to sprout.
